We've recently rolled out a brand-new avatar system that should make setting you account avatar super-simple.
To begin, login to your Singletracks account and click the "My Account" dropdown in the upper right, and then click "Edit Profile."
Next, scroll down and look on the right side of the page for the "Member Photo" block. Under "Source," select which source you'd like to use.
"Facebook" only works if you have a Facebook account linked to your Singletracks account. "Gravatar" only works if you have an active Gravatar account associated with the same email account that your Singletracks account is registered to. But the newest option, "Custom," works for everyone.
For "Custom," simply select that option, then click "choose file" to upload an image for your avatar from your hard drive. Click "save," and you're good to go!
